Zucchini Tomato Spaghetti Squash with Pesto

Zucchini Tomato Spaghetti Squash with Pesto is a fresh, tasty meal. Packed with vegetables, this dish is a healthy plant-based dinner.

Zucchini Tomato Spaghetti Squash

A dish full of veggies is the best kind of dish!

I love when it's easy to eat vegetables. For me, that means a meal that makes a lot (read: tons of healthy leftovers) and a meal that is flavorful.

If it tastes incredible, I'm more likely to eat it. And if it makes a large volume then I have servings for days.

This dish meets both those criteria. Spaghetti squash produces a TON of volume. And the fresh basil in the vegan tofu pesto is so tasty.

Zucchini Tomato Spaghetti Squash with Pesto is the perfect dish to prep on the weekends and enjoy all week! I don't know about you, but I never get tired of pesto. And the spaghetti squash kind of makes it seem like I'm eating pasta. But it's even healthier!

Now, there are a couple moving parts in this recipe. You basically have three separate steps to complete the dish.

First, you cook the spaghetti squash. This is easy because it's hands-off. Just scoop out the seeds and pop it in the oven.

Then you make the pesto. Throw basil and the other pesto ingredients into a food processor until it creates a smooth paste.

Finally, you cook the zucchini and tomatoes. Sauté them really quick to soften them up.

After that, you just put everything together! No need to freak out about the multiple steps. This recipe begs for multi-tasking. You should be able to easily make the pesto and get the zucchini cooking while the spaghetti squash is still in the oven.

But I don't want to get ahead of myself. Let's talk ingredients!

Zucchini Tomato Spaghetti Squash


In a dish that's mostly vegetables, most of the ingredients will be, well, vegetables! Eating a variety of veg helps you get all the nutrients you need.

  • Spaghetti Squash: Spaghetti squash is a fun type of squash named because the tender part of the squash looks like spaghetti. They are in season late summer and early fall, so buy them when they're fresh!
  • Zucchini: Use green zucchini for more color variety in this dish. More colors = more antioxidants.
  • Cherry Tomatoes: For a fresh pop of color, choose red tomatoes over yellow.
  • Garlic: Garlic adds tang and umami to the dish and helps flavor the veg.
  • Vegetable Broth: We'll use vegetable broth to cook the zucchini and tomatoes, instead of oil. Make sure you buy one with no added salt or sugar!
  • Basil: Before you use all of it in the pesto (see below), save a couple leaves to use as a topping. A fresh pop of flavor at the end makes a huge difference.

Tofu Pesto

We'll be making vegan pesto (of course) so there are a couple substitutes to a traditional pesto recipe.

  • Fresh Basil: No substitutes here. Basil is the star of any pesto recipe. I call for 2 ounces, which is a lot. But it's worth it for all the flavor!
  • Extra Firm Tofu: Traditional pesto recipes use oil to create a paste. We'll use tofu instead as an extra punch of protein and nutrients that oil doesn't have.
  • Nutritional Yeast: Pesto usually has parmesan cheese, but we can use nutritional yeast to bring that cheesy flavor. AND (as the name suggests) nutritional yeast is filled with good-for-you nutrients, unlike cheese.
  • Walnuts: I prefer walnuts in my pesto because of their proven brain benefits, but pine nuts will work just fine.
  • Garlic: For tang and umami.
  • Apple Cider Vinegar: ACV adds more tang and helps thin out the pesto.
  • Salt: Salt is a flavor enhancer. It's especially crucial in this dish because we're using nutritional yeast. Salt really brings out the cheesy flavor.

How to make Zucchini Tomato Spaghetti Squash with Pesto

It seems like a lot, but don't freak out. You'll have this dish ready in no time. AND since it makes so much, you definitely won't have to cook for a couple days!

Step 1. Start by cooking the spaghetti squash. I give simple instructions here, but if you're interested in a more in-depth tutorial check out my post on how to cook spaghetti squash.

Step 2. Using a large knife, cut the top and bottom off of a spaghetti squash. Cutting off both ends isn't 100% necessary, but I find it makes it much easier to cut in half. If you have a flat end on the bottom and a flat end on the top you can feel stable when you cut.

Step 3. Slice the squash in half lengthwise. Then scoop out the seeds.

Step 4. Place the spaghetti squash halves face down on a baking sheet and bake for 30 minutes, until just tender. Note that this is a shorter time than I suggest in my spaghetti squash tutorial -- we want fresh, just done veggies for this recipe.

Step 5. While the spaghetti squash cooks you can start on the other two parts of this dish. First, prepare the tofu pesto. Add all the pesto ingredients to a food processor and blend until smooth. Taste for salt.

Step 6. Then move on to the zucchini and tomatoes. Heat a splash of vegetable broth in a large nonstick pan over medium heat. Use only a tablespoon or two or else you'll end up with tons of liquid in the pan.

Step 7. Add the sliced zucchini and sauté for 15 minutes, until they are just soft. Add extra vegetable broth if they start to stick. (But not too much! -- You shouldn't use more than 1/4 cup total.)

Step 8. Add the cherry tomatoes and minced garlic to the pan. Cook with the lid on for 3 minutes. Then remove the lid and cook off any remaining liquid for 30 seconds.

Step 9. When the spaghetti squash is cool enough to handle, use a fork to scoop out the insides. Add the spaghetti squash to the pan with the zucchini and tomatoes. Stir to combine.

Step 10. Mix the pesto into the squash or serve in bowls first and mix the pesto individually into each bowl. Top with fresh basil. Enjoy!

I was in the middle of making your Tempeh Swiss Chard recipe and noticed you never mentioned how much Swiss Chard to add. I just added the sautéed tempeh towards the end and mixed it all together. I also reduced the amount of red pepper flakes.
Hi Jenny - so sorry about that! It should be one bunch. I've updated the recipe to include the correct information. Thanks!

This looks fantastic! Do you think we could substitute butternut squash for the acorn squash?
Hi Elissa - you can definitely use butternut squash. In terms of texture, the pie will be exactly the same with either squash. I'd recommend using the volume measurement instead of the weight measurement, since the density of butternut squash isn't exactly the same as acorn squash. Also, the flavor of the butternut squash might come through in the end pie a bit more prominently than acorn squash does, but I don't think it will be too noticeable. Let me know how it goes if you try with the butternut squash. I'd love to hear!

Hi Katherine - yes, I did use fire-roasted tomatoes when I photographed this recipe. I don't call for fire roasted in the recipe because it's intended to be a basic, use-in-anything type recipe. But it does taste delicious with the fire roasted tomatoes! -- Elizabeth

As someone who has pretty much never successfully scrambled tofu - this was the best scrambled breakfast dish I've ever had - better than eggs and the seasoning is truly delicious!!
Oh, amazing! So glad to hear it went well :) This is definitely one of my favorites - thanks for sharing your kind words! -- Elizabeth

It's close to my bedtime, but I've been thinking about making this recipe all day, so I made it just now. After all, it only takes 15 minutes! I used what I had, so I made a few minor substitutions...white beans for cannellini, purple basil from my garden, red onion for more color, and date syrup for maple. I took a bite before putting it in the fridge for tomorrow, and oh my! It's delightfully flavorful, light, and fresh-tasting. Thanks for sharing your recipe!
Hi Linda - I'm so glad you liked the recipe - and your substitutions sound great (wish I was growing purple basil in my garden!) Thanks so much for sharing!

Hi, is this ice cream soft to scoop out? I always find my ice creams are hard.
Hi Carol - yes, this ice cream is soft if you let it thaw a few minutes after you take it out from the freezer. It can become pretty solid if it's in a deep freezer, but still thaws quickly on the counter. Hope this helps!

Hi Elizabeth! I found you by searching for plant based Catholics! There are very few of us! Thank you for your site and sharing recipes!! I look forward to trying these muffins! Can sugar be reduced safely in most of your recipes? -JMJ-
Hi Katherine, Thanks so much for reaching out! Glad to meet another plant-based Catholic - agree, there are so few of us. As for sugar, I never use white granulated sugar in any of my recipes. Most use maple syrup or date sugar/date syrup. I'm not sure if this is what you mean, or if you're asking about reducing the amount of date sugar that the recipe calls for. If that's the case, it really depends on the recipe. A lot of the baking recipes have specific ratios of flour to sugar and wet to dry, so it may not go well if you change the amount of sugar. I hope this helps, but if I didn't answer your question, please let me know. Also happy to advise on a particular recipe if you're looking to change it. Let me know how I can help :) Elizabeth

Love this vegan lentil/mushroom stew! For some odd reason, I had never thought to put mushrooms into my lentil stew. Thank you for a wonderful addition to my recipe box!
Hi Sharon - I'm so glad you are enjoying this recipe (mushrooms are so good!!). Thank you for taking the time to share :) Elizabeth

Hello, I found you on FB and really enjoy your Catholic Plant Based GF information & recipes. About the Chickpea beet burgers: if the beans are dried and not cooked, do you think it is enough cooking for the beans? If beans are not cooked completely I have read they are toxic with phytic acid & also cause digestive problems. I am just wondering and will leave it to you to decide/research. To be safe I am toasting canned garbanzos and trying that way out. God Bless
Hi Geraldine, Thanks so much for reaching out. In the beet burgers, the beans do get cooked when the burgers are cooked. You soak them first and then incorporate the beans into the burger patty, then cook the patty. I find that this is the best way to achieve the proper burger texture - if you use pre-cooked beans or canned beans the burgers are mushy and don't get crisp. Your solution of toasting the beans sounds like a great idea to completely ensure the beans are cooked fully - I hope that it worked for you and your burgers turned out well! -- Elizabeth

Can you leave nutritional info for your recipes? Serving size/calories would be so helpful! Trying mushroom lentil stew tonight! and looking forward to crispy chickpea stuffed sweet potatoes very soon. Thanks for creating healthy, attractive recipes!
Hi Katie - so excited to hear that you are trying some of my recipes! I'd love to hear how they go. I haven't posted nutritional information for my recipes because I know it can be difficult for some people with disordered eating to see nutrition facts. I've gotten a lot of requests to add them recently, so I'm working on a solution that can provide information for those who want it but not be triggering for others. In the meantime, if you're curious about the nutrient info about a particular recipe, I recommend using Cronometer. It's a website/app to track and understand nutrient info and I think it does a great job of emphasizing all the nutrients (not just macros). I hope this helps! Please let me know if I can help in any other way.

U mentioned date sugar on this recipe but it’s not in the instructions. I know u add it but just in case u wanna add to instructions. Love ur recipes! Thank u. I’m thinking of going to vegan a little nervous tho lol
Hi Vickey - thanks so much for catching that! I am updating the post now. So happy to hear you enjoy my recipes. And exciting that you are thinking about going vegan!! If there's anything that I can do to help, please let me know.

I'd love to try this soup. What are the nutritional values, like how much fat does it contain, carbs, etc.
Hi Sr Maureen - I usually don't post macronutrient information because I know each person has their own goals and I don't want to encourage or discourage anyone's specific goals. But I often use Cronometer as a tool to understand the nutritional profile of my recipes. I plugged the ingredient information for this recipe into Cronometer and got the following nutrient information per serving: 521 calories, 44g fat, 23g carbs, 16g protein. I hope this helps. Please let me know if you have any other questions and if you try the recipe!

Thank you I have been doing the fruit and oatmeal, etc for years and I love it. I will try the pears. I refrigerate my left over oatmeal and with a touch of milk or fruit juice liquid it’s fine the next day. Just a warning about tofu; it interferes with some medicines especially Thyroid medicine. Thank you for the short prayers, there are lovely.
Hi Martha - thank you so much for your kind words. I'm glad you like the prayers! As someone who doesn't take any medications I have no issues with eating tofu and encouraging others to eat it too (it's a great source of protein!). That said, you should always consult with your doctor about possible interactions with medications. I have plenty of recipes without tofu, so hopefully you can find things that work for you!

When you say shape into a rectangular loaf, what dimensions? 1/2 thick by 8 inches long or?
My loaf was about 7" long and 4" wide with about 1" of height. Then I sliced it 1/2" thick along the long end to get 12ish biscotti. I will clarify this in the post! Let me know if this makes sense and if you have any other questions.

Hi Could you please confirm two things:1. The amount of salt. Seems like too much. 2. The directions say there is lemon juice in the dressing but it’s not listed under ingredients. ThanksL.
Hi there! Confirming that the two teaspoons of salt in the dressing is correct. I didn't salt the cauliflower when roasting it or the salad after it was done, so this amount of salt was perfect. If you're concerned about it you can decrease the amount of salt in the dressing and then add more at the end if you need it. As for the lemon juice, SO sorry about that! It was a typo in my directions and I've removed it now. Hope this helps :)

This looks lovely! Do you have a recipe for the red pepper hummus also? Thank you!
Hi Martha! I don't have a recipe for red pepper hummus on my site. I suggest taking a traditional hummus recipe and blending in roasted red pepper.

Hi, these look amazing. I was wondering, could I used powdered peanut butter in place of creamy for the recipe? thanks
Hi Grace! There is already some powdered peanut butter in this recipe, so adding more might make the texture more gluey. Also, the real peanut butter adds some fat, which helps create flavor. That said, if you want to use powdered peanut butter, I would suggest mixing it with a high-fat liquid like coconut cream and then measuring out 2/3 cup. Hope this helps! Let me know how it goes :) -- Elizabeth

You mention using vegetable broth in your introduction but it isn’t included in the recipe
Hi Becky - thanks for pointing this out. I have removed mention of vegetable broth from this post. You do not need any vegetable broth. The mushrooms will release natural liquid which will prevent any sticking. -- Elizabeth

thank you for the oil free recipe. I'm getting introduced to wild Bolete mushrooms here in Colorado, and everyone sautes Bolete's in butter or olive oil. I'm on a veggie, oil free regimen for heart health reasons. and your recipe suggestion may fill the bill. I can't wait to give it a try.
